Title: Heat-exchange type blower
Inventor: SUMIYA KATSUHIKO
IPC: F24F7/08
Filed: 1982-10-08
Abstract: PURPOSE:To provide a smooth air flow and to lower the flow resistance of air for improving an air blowing capability, while simultaneously enlarging an effective heat transmitting area, by forming a streamlined part inclined or curved towards at least one air inlet section or outlet section of recessed area defined between blades constituting heat-exchanging impellers. CONSTITUTION:An impeller 18 has its air inlet sections 16a, 16b and air outlet sections 17a, 17b on opposite surfaces, or at least one of them formed as a streamlined part A inclined or curved, and thus provides a very smooth air flow. This results in eliminating a vortex which would be otherwise observed in the air inlet sections 16a, 16b and the air outlet sections 17a, 17b. The air flow resistance is lowered, while the air flow rate is increased, and thereby significantly reducing the area which is not contribute to the heat exchanging function. Thereby, an effective heat transmitting area can be enlarged despite the reduction in an apparent transmitting area.
